SULKY-PLOW.

SPECIFICATION forming parser Lettere Patent No. 249,501, dated November 15, l1881.

` Application filed October 10, 188i. (Model.)

To all whom e'tmay concern Beit known that I, EDWIN M. CARROLL, of Pittsford, Hillsdale county, State of Michigan, have invented a new and useful Improvement in Sulky Attachments for Flows; and I do llere- .bydeclare that the following is a full, clear,

and exact description of the same, reference being had to the accompan yin gdrawin gs, forming part of this specification, in which- Figure l is a perspective view of my irnproved sulky attachment for plows with plow attached. Figs. 2, 3, and 4 are detail views of the same.

My invention relates to sulky attachments for plows, and is an improvement ou my Patent No. 246,080, granted August 28, 1881; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth.`

III the accom panyin gdrawin gs, a represents a crank-axle having its vertical furrow-side arm'longer than its land-side arm. On :the horizontal portions of these arms supportingwheels b l), of usual construction, are applied.

e is a sulky-frame composed of a bent metal bar. rlhis frame is ot rectangular form at its forward end, and one of its longitudinal par.-

` allel sides is clipped to the horizontal part of the crank-axle, while its other side is clipped to the inner side of the guide-tongue A. The vertical portions d of the frame care extended down behind the axle and pass loosely through vertical] y-slidin g blocks e, which are provided, respectively, withlperforated lugs. Through the `perforations g of the lugs the angular ends of parallel guide-rods h are passed loosely and allowed freedom to articulate up and down. The guide-rods h extend back and are united, as shown, or in anyother suitable manner. Upon these guide-rods the rear portion ot' the plow-beam t' is suspended by means of a rocking and rolling bar, 7c, clipped directly upon the beam i, and by blocks or hangers j, attached to the guide-rods h. By means of the bar lc, the ends of which are loosely fitted in the blocks j, and hooked eyebolts l, clip-plate m, and `nuts n, a clamping device is formed which affords great convenience while a small plow-beam is being substituted fora larger one or a large beam for a smaller one. By turning down the nuts far enough to allow the hooked eyes of the bolts l to clear the bar lo `the eyebolts can be disconnected from the bar and withdrawn from the beam, and when thus withdrawn the beam and plow will be free to be removed, so far as this clamping device is concerned. lWith other clamps it is necessary to remove the nuts from the bolts and to withdraw the bolts from the clip-plate before the beam and plow can be removed.

Forward of the clamping device le, l, m, and n another similar clamping device, c', l', rn/,and

m', is provided, and by means of this device like facilities for substituting a large beam for a smaller one or asmall beam for a larger one are afforded. In both of these clamping devices the plates m m are slotted or made in forni ot' oblong lin-ks, and the hars kand e are made long enough to permit lthe hooked eyebolts to be moved apart or together laterally to suit different widths of' beam `and the bar et is provided Vwith perforated ears e2, to which a pitman is connected.

The sliding blocks e are connected by adjustablepit'men t r s u to a double-crank shaft, o, which has one of its cranks, p, set just opposite the other, q, as shown.

The pitmen consist, respectively', ot' astrap having holes g and a rod, the latter being attached by its lower bent end to a lug of a block, e, and hooked by its upper hooked end into one or the other ot' the holes in one of the straps t or u. The double-crank shaft is pivoted to the flame c and tongue A near the rear end. thereof. The cranks p and g lie in the same plane,and one extends back and the other forward. In some instances the cranklshaft will be pivoted wholly to the frame c and have no connection directly with the tongue A. One end of the crank-sbatte is connected by an upturned extension, o, thereon, and a rod, w, to a hand-lever,x, said lever being., as usual, provided with a spring-pawl, y, which engages in a curved rack, a. By means ot' the cranks p and q of the shaft o the sliding blocks will be moved in opposite directions upon the guiding extensions el of frame c' when the lever x is moved forward or backward, and, owing to the sliding blocks moving in opposite directions, the guide-rods will be caused to rock the bar k, with the plow-beam, tothe right or left, accordingly as t-he lever is moved,

and thus the plow will be winged or leveled to suit the elevations or depressions of thel ground; and by having the guide-rods free to articulate in the holes g in the lugs of the blocks e the wheels b of the sulky are free to rise and fall in passing over obstructions without affecting the plow or its connections; or, in other words, the plowshare will remain at its adjusted plowing depth while the wheels are rising or falling.

Forward of the double-crankshaft o a single crank, b, is pivoted to the sulky-frame, near the rear end thereof. To this shaft the plow-beam is connected by means of a laterally-adjustablepitman, c d', and the clamping device e', The crank-shaft b is connected to an upturned extension, fi', on one of its ends, and by a rod, j', to a lever, k', which is provided, as, usual, with a spring, l2, which engages with a curved rack, lm2.

By means of the crank b and its connections the plow can be raised bodily out of the furrow or lowered, as may be desired; and by means of the clamping devices and the sliding pitman-strap the plow can be adjusted either to the right or left, as may be desired. While raising or lowering the plow the guide-rods h articulate in the holes ot' the lugs of the blocks e, while the sliding blocks]- slide upon therods, and thus do not interfere with the movement of the plow. The sliding blocks j do not requre to slide while the plow is being winged Y or leveled, and therefore my invention for effecting the winging or leveling of the plow could as well be carried into effect by attaching the bar 7c to other hangers or supports for its ends. These blocksj might have their upper edges similar in form to their lower edges,

Power is applied directly to the plow-beam, and an adjustable neck-,yoke is applied to the outer end ofthe sulky-tongue in the usual manner. v

What I claim as my invention, and desire vto secure by Letters Patent, is-

' o, having opposing cranks, connecting pitmen,

sliding blocks e, and frame c substantially as described.

3. The combination of the crank-shaft b', pitman d', clamping device e l m', articulating guide-rods h, bar k, and longitudinally-sliding blocks j, substantially as and for the purpose described.

4. In combination with the beam i, the clamp- `ing device consisting of the bar e', provided with perforated ears e2, the screwthreaded hooked eyebolts Z, link m', and nuts n', s'ubstantially as described.

5. The clamp im and plow-beam fi, in combination with thelaterally-rockingbark, blocks 1', and guide-rods h, substantially as and for the purpose described.

6. rlhe combination of the bar k, havin g both a rolling and rocking motion, beam z', articulating guide-rods ll, longitudinally sliding blocks j, vertically-slidin g blocks e, frame c d, and cran k-shaft o, having opposing cranks, substantially as described.

7. The two loosely-fitted sliding blocks e, connected to the plow-beam and frame c d, and to the doi1blecrank shaft by suitable intermediate means, and operated by a lever from the drivers seat, whereby one slidin gblock is raised and the other lowered simultaneously,and the plow thereby winged or leveled, substantially asdescribed.
